oc  edenti  volumen,  quo  omnia  genera  omnesque  Ba- 
cillariearum  species  hucusque  cognitarum  cum  viventium 
tum  fossilium  una  continentur,  liceat  mihi  exponere  ma- 
ximam  difficultatem,  quae  occurrit  in  quibusdam  generibus 
amplissimis  elaborandis,  in  quibus  nec  synonymiam  nec 
alias  pra^cipuas  qusestiones  omnino  persolvere  potui. 

Enormis  specierum  copia,  frequens  difficultas  earum 
identitatem  comprobandi,  defectus  speciminum  authentico- 
rum,  innumera  studia  nuper  in  lucem  edita,  absentia  ico- 
num  multarum  specierum,  instabilitas  systematum  de  Ba- 
cillarieis,  penuria  descriptionum  plurimarum  specierum  tara 
clari  Ehrenberg  quam  Schmidt  etc,  commutatio  ad  unicuin 
typum  (micromillimetra)  mensurar;im  microscopicarum  me- 
thodis  vetustis  diversisque  exhibitarum,  ad  mei  operis  pro- 
gressum  impedimenta  fuerunt  ejusque  editionis  dilationem

conspicuos  in  rhaphes  seu  pseudorhaphes  praesentia  vel  ab- 
sentia  institutos  anteponendos  existimavi.  Quomodo  reve- 
ra  millia  et  millia  specierum  secundum  notas  endochro-

tuissem?  Nihilominus,  ubi  potui,  characteribus  structurse
